IMPROVEMENT IN WOOL-CARDING MACHINES.

Specification forming part of Letters Patent No. 40,13 l dated September 29, 1863.

To all whom it may concern Be it known that I, DANIEL TAIN'JER, of Worcester, in the county of Worcester and State of Massachusetts, ha-ve invented certain new and useful Improvements in Wool-Carding Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figures l, 2, and 3 represent the sides of the common or ordinary cast-iron frames of tie first breaker, second breaker, and finisher of wool-carding machines, respectively, while Figs. 4, 5, and 6 represent the sides ot' the frames of the same machines as improved by me. Figs. 7 and 8 represent detached parts, and will be referred to hereinafter.

The reason why Wool-carding machineframes are made different lengths for rst and second breakers and different length on doffer77 end of finisher is, first, the irst breaker has much more machinery and gearing on or attached to the feed end A of the machines than the second breaker and iinisher have. To the first breaker are attached the feedapron and burringmachine, which are supported on the horizontal part of the frame A. The second breaker and finisher, havingno feed-apron or burring-machine attached,vare made shorter than the first breaker, as indicated in Figs. 5 and 6. The doft'erend B of the finisher-card, where the condenser is put on, must be lower down to receive the condenser than the doer end to the breakers, and also shorter. Consequently all three frames to a set of wool-carding machines are made differently, and required different patterns as previously made.

The arch C of a woolcarding machine is commonly made with two an ges or ribs, D E, for the purpose of supporting the puppetheads.7 (so called) or stands e, in which the bearings or journals h rest or run. Said stands or puppet-head stems, being fitted to a cap or casting, a, screwed or bolted on top of the arch, the lower ends passing through holes in the ange E of the arch C.

My first improvement relates to a plan or device to save the expense of drilling, cutting, or corin g the holes in the top or outside ilange, while at the same time securing the proper and necessary bearings for the puppet-head A8 three views-viz., a top stems. This I accomplish by cutting notches, openin gs, or spaces in my arch-pattern on the. top or outside iiange, so as toy have an open space (at such places as it may be desirable to put in the puppet-head stems) cast in said arches, in connection with the use of the peculiarly-constructed cappieces a, which are so made that the molding or bead c ts into the outer edge ot' the opening in the flange D, while the ends of the cap-piece a rest upon the top surface of the same flange, thereby making a lock joint or connection, which iusures the permanent relative position of the cap-piece and puppet-head stems as respects the main cylinder G, which is supported in bearings upon the iron frame F.

In Figs. ing or bead c, is shown in place, while in Fig. or plan, side, and central or cross-section-of the cap a are given, showing all the parts on an enlarged scale.

To the central and main part, F, of the frameI attach ends, arms, or wings A and B, of such length and pattern as are rendered necessary by the kind of card or machine ordered.

In constructing a card-frame with each side in three separate pieces, I found a difficulty in attaching the two ends, arms, or wings A and B to the main portion ot the frame F, since these ends, arms, or wings had a great tend- I ency to sag or draw off from the main portion of the frame, and thus throw the machinery supported thereon out of line and its relative and proper position as respected the main cylinder G. In order, therefore, to secure the arms or wings to the main part F in such a manner that they would always retain a iixed relative position, I constructed or formed the Wings or arms A and B with ear-pieces 'i t', to project by and bear against the inside of the main frame F, and also with a hook or projection, f, to t into a corresponding notch or hook, d, formed on the main frame, all as clearly indicated in Fig. 4 of the drawings.

By reference to the drawings it will be seen that as the arms or wings are dropped down into position, owing to the aring of the bottom of the frame F against the edges of which the ends of the wings bear, and the wedge-like form of the hooks or projections j', a very close and secure joint and connection is obtained even without the use of bolts,

4, 5, and 6 a cap, a, with its moldand one, too, that Will sustain the arms or Wings from any downward deection, thereby insuring a fixed and permanent relative position ofthe wings and the machinery connected therewith during the operation of the machine.

In Fig. 7 one of the end pieces is shown on an enlarged scale, and from which it Will be seen that With bolts passing through the earpieces z' i, in combination with the hooks d and f, a good7 rm connection with the main part F of the frame, is obtained, and one, too, that permits the use of loosely-fitting bolts.
